Far infrared LED, or far infrared light-emitting diode, is a type of semiconductor device that emits far infrared radiation. It has been widely used in various fields such as medical treatment, health care, agriculture, and industrial applications. In this article, we will introduce the far infrared LED industry, including its working principle, application fields, market status, and future development trends.

Working Principle of Far Infrared LED

The far infrared LED is a semiconductor device that converts electrical energy into far infrared radiation. The working principle is based on the photoelectric effect. When a forward voltage is applied to the PN junction of the semiconductor material, electrons and holes are generated. The electrons move to the conduction band and release energy in the form of photons when they recombine with holes. The photons emitted by the far infrared LED have a wavelength between 7.5μm and 15μm, which falls within the far infrared region of the electromagnetic spectrum.
